12V to 24V. The voltage of urea collapse in Dongfeng Fuluka depends on the specific vehicle type and the electrical system used. When the solenoid valve is opened, its voltage will reach the range of 12V to 24V. When the solenoid valve is opened, the urea solution can flow out of the urea tank and enter the NOx catalytic reducer (SCR) to remove the NOx in the waste gas through thermochemical reaction and purify the waste gas. Therefore, the voltage of solenoid valve to control urea collapse must meet the power supply requirements. Too high or too low voltage may lead to urea collapse failure or burning loss. Dongfeng Furuika is a sub-brand of Dongfeng Motor Co., Ltd., with the brand connotation of "creating wealth in urban and rural areas and people starting businesses" and the brand proposition of "giving happiness to simple strugglers".
